[PATCH v9 09/20] target/riscv/cpu.c: limit cfg->vext_spec log message |

Inside riscv_cpu_validate_v() we're always throwing a log message if the
user didn't set a vector version via 'vext_spec'.
We're going to include one case with the 'max' CPU where env->vext_ver
will be set in the cpu_init(). But that alone will not stop the "vector
version is not specified" message from appearing. The usefulness of this
log message is debatable for the generic CPUs, but for a 'max' CPU type,
where we are supposed to deliver a CPU model with all features possible,
it's strange to force users to set 'vext_spec' to get rid of this
message.
Change riscv_cpu_validate_v() to not throw this log message if
env->vext_ver is already set.
